...a scientist's achievement may lie in many different areas: As an innovator (new discoveries, new theories, new concepts), as a synthesiser (bringing together scattered information, sharing relationships and interactions, particularly between different disciplines, like genetics and taxonomy), as a disseminator (presenting specialized information and theory in such a way that it becomes accessible to non-specialists [popularizer is a misleading term]), as a compiler or cataloguer, as an analyst (dissecting complex issues, clarifying matters by suggesting new terminologies, etc.), and in other ways.'

Ernst Mayr to Will Provine (1979), quoted in W. Provine. 2005. Trends in Ecology and Evolution 20:411

Richard Feynman's Advice to Koichi Mano on Picking Problems in Science

The worthwhile problems are the ones you can really solve or help solve, the ones you can really contribute something to. A problem is grand in science if it lies before us unsolved and we see some way for us to make a little headway into it. I would advise you to take even simpler, or as you say, humbler, problems until you find some you can really solve easily, no matter how trivial. You will get the pleasure of success, and of helping your fellow man, even if it is only to answer a question in the mind of a colleague less able than you. You must not take away from yourself these pleasures because you have some erroneous idea of what is worthwhile.

You met me at the peak of my career when I seemed to you to be concerned with problems close to the gods. But at the same time, I had another Ph.D. student (Albert Hibbs) whose thesis was on how it is that the winds build up waves blowing over water in the sea. I accepted him as a student because he came to me with the problem he wanted to solve.

...No problem is too small or too trivial if we can really do something about it. You say you are a nameless man. You are not to your wife and to your child. You will not long remain so to your immediate colleagues if you can answer their simple questions when they come into your office. You are not nameless to me. Do not remain nameless to yourself -- it is too sad a way to be. Know your place in the world and evaluate yourself fairly, not in terms of ideals of your own youth, nor in terms of what you erroneously imagine your teacher's ideals are.

Research opportunities for undergraduates

These consist of assisting graduate students, post-docs, and me in aspects of our research; independent studies; internships and senior theses (requiring at least a 2 quarter, and preferably 3 quarter, commitment). The senior thesis is a research project that the student and I design together, to match both of our interests. Some examples of senior theses that I supervised since 1990 are Locomotor abilities and habitat choice in anolis lizards; Cost of the facultative dauer stage in nematode life histories; Barn owl traffic-related mortality and its implications; Conflict resolution for endangered species problems; Diet choice in hydra; Effects of the 1976 Oceanic Regime Shift on Coho Salmon Populations; A Meta-Data Dictionary for Santa Cruz County GIS; An Environmental Perspective to Using Individual Transferable Quotas (ITQs) to Manage New England Groundfish; Insect Behavior and Trap-Crop Design; Effects of Nodulation Outweigh Compensatory Growth Response After Minereal Nitrogen Deprivation in Medicago polymophra; Spatial and Temporal Patterns of Glucosinolates in Raphanus sativus After Induction by Jasmonic Acid; The Impacts of Entrainment on Larval Fish Populations; Life history variation, growth and smolt transformation in steelhead trout; An Analysis of Juvenile Survival Rate to Smolt Age, in the San Lorenzo River; Econmic analysis of vessel price as a response to fishery regulation; Species-area relations in the context of marine reserves; and Detecting density dependence in seal population dynamics


John Bahcall's advice to young scientists

•Choose important problems

•Get involved with real data

•Bring the most powerful analytic tools to bear on the problem at hand

from W.H. Press. 1997. Understanding data better with Bayesian and global statistical methods. pg 49-60 in Unsolved Problems in Astrophysics (J.H. Bahcall and J.P. Ostriker, editors), Princeton University Press


Hans Krebs's advice to students who ask about how to attain distinction in science:

To attain distinction in scientific research you must

--get a post-doctoral Fellowship, which will give you the time and opportunity to test yourself;

--attach yourself to a centre of excellence;

--work hard and make the fullest use of the time and facilities that the Fellowship affords;

--from time to time, search your heart critically, with the help of objective critics, to find out whether you really possess the right mixture of qualities -- urge, commitment, imagination, humility-- which are the roots of creativity in science.

from HA Krebs.1981.Remiscences and Reflections. Oxford University Press (pg 179)

In solving a problem of this sort, the grand thing is to be able to reason backward. That is a very useful accomplishment, and a very easy one, but people do not practise it very much. In the everyday affairs of life it is more useful to reason forward, and so the other comes to be neglected. There are fifty who can reason synthetically, for one who can reason analytically...Let me see if I can make it clearer. Most people, if you describe a train of events to them, will tell you what the result would be. They can put those events together in their minds, and argue from them that something will come to pass. There are few people, however, who, if you told them a result, would be able to evolve from their own inner consciousness what the steps were which led up to that result. This power is what I mean when I talk of reasoning backward, or analytically.
